Application filed July 18, 1924. Serial No. 726,833.

may concern:

SNELL and WILLIA S. BmnwELL. citizens of the United States, residing atIndianapolis,

in the "5 county of Marion and State of Indiana, have flanges of thecarburetor 3 and the intake 1 of the hub, each invented new and usefulImprovements in Mixers, of which the following is a specification.

Our present 1 nvention has reference to a fuel mixing device forinternal combustion engines.

Our object is bureter and the ternal combustion engine,

to arrange between the carmtakemamfold of an 1na gasket having journaledtherein two fans whose blades are arranged at opposite pitches wherebythe intake of the-fuel contacting with the fans will impart motion tosaid fuel will be and thoroughly ted into the piston cylinders,

the said fans will turn in opposite naled thereon, the hubs of fanmembers 10 and 11 respectively. The blades of the fans arearranged atopposite pitches so as to impart a beating action against the vapor thatpasses from the carburetor into the intake manifold 4. The fans arerevolved by the contact of such gases. .The gasket- 1 is provided withone or more air inlet ports 12, the same being preferably arranged adjacent to the fan nearest the intake manifold 4. W

With our improvement, it will be noted that the rotation of the fanswilli impart a beating action against the vaporized gas that passesbetween the carbureter and the intake manifold to more effectively breakup the particles thereof so that. the fluid will be delivered in abetter state of combustibility to the engine cylinders: Also. byproviding the ports 12, itwill be seen that fresh air to mix with theigaseous fluid and it is believed that the fore oing descripwhen taken inconnection with the will fully set forth the improvethe advantagesthereof.
